Using the adoption and expansion of wired telegraph in China during the late 19^(th) century,this paper investigates the effect of cost reductions for knowledge exchange on China’s industrial growth before the outbreak of the War of Resistance Against Japanese Aggression(1931-1945),thus testing Baldwin’s theory of“the Great Convergence”in which developing countries are empowered by information and communication *** on panel data of 1858-1937,we found that wired telegraph access had a significantly positive effect,as well as a long-term growth effect,on the entry of industrial *** mechanism analysis indicates that wired telegraph access accelerated early-stage industrialization in localities by encouraging market integration,human capital accumulation,and auxiliary commercial *** a few countries firmly asserted their telegraph sovereignty and set up their own workforce educational system during telegraph *** explains why the Great Convergence arising from technology importation only occurred in a small number of *** findings contribute to understanding the source of China’s modern industrial progress,as well as why global inequities remain.

本文以20世纪80年代实施的农村水电初级电气化项目为能源供给冲击,采用队列DID策略检验了传统能源向清洁电力转型对农村人力资本的长期影响。研究发现,学龄前儿童接触农村电气化项目能够增进其青少年时期的人力资本,使其受教育年限提高0.17年,同时使初中入学率和高中入学率分别提高2.2%和3.4%。机制分析表明,农村电气化通过收入创造克服了“能源阶梯”难题,从而实现了可持续的能源清洁转型,同时也为改善地区和家庭内部的教育环境提供了可能。此外,该项目通过替代家庭传统能源,改善了个体健康状况。本研究揭示了清洁电力使用与人力资本增进之间的关系,为推动新时期的农村能源清洁转型,加快农业农村现代化提供了学术支撑。

本文利用19世纪末有线电报引入并在中国扩张这一外生技术变革,研究了知识交换成本下降对中国工业增长的影响,从而检验了Baldwin(2016)有关信息与通信技术塑造少数发展中国家“大合流”的理论。基于1858一1937年的面板数据,发现有线电报接入对工业企业进入产生了显著的正向影响,且具有长期增长效应。机制分析表明,有线电报的接入通过促进市场整合、人力资本积累和辅助性商业组织发展三条路径推动了当地的早期工业化。电报技术引入过程中牢牢掌握电报主权并构建自主性电报人才培养体系一定程度上解释了技术引入催生的大合流为何仅在少数国家发生。本文的发现有助于理解近代中国工业增长的来源,也有助于理解世界不平等为何仍在持续。

二氧化硅气凝胶具有极高的透光率,在辐射探测领域中可用作Cherenkov辐射探测器的关键组成部分。然而,二氧化硅气凝胶在10 mm厚度要求下,在550 nm波长处实现透光率大于80%仍然是一个颇具挑战性的问题。首先采用乙醇滴定实验构建了三元溶液互溶性相图,通过在不同相区域内选取合理参数,实现了从透明溶胶到透明气凝胶的制备。进一步研究了高透明二氧化硅气凝胶密度、微观结构及其透光率三者间的影响关系,结果表明二氧化硅气凝胶的粒径和孔径会影响气凝胶透光率。综上所述,采用溶胶–凝胶法,优化选取互溶区的相点参数成功制备了厚度为10 mm,在550 nm处透光率为80.3%的高透明二氧化硅气凝胶,满足了Cherenkov辐射探测器对气凝胶辐射体光学参数的基本要求。

利用树木年轮探测历史时期气候因子变化具有较大潜力。本研究首次基于大兴安岭西北部额尔古纳地区的白桦(Betula platyphylla)树轮样本,重建了该地区1902~2019年(EPS>0.85)共118年6~7月的降水量变化,重建模型的方差解释量为30.4%;同时,本重建与邻近地区的历史资料有较好的对应关系,进一步验证了该重建序列的可靠性。该重建序列显示,自1902年以来本区域的降水变化相对平稳,共经历了8个偏干旱期(1903~1916年、1924~1929年、1937~1941年、1949~1954年、1965~1972年、1979~1983年、1990~1993年和2001~2007年)和8个偏湿润期(1917~1923年、1930~1936年、1942~1948年、1955~1964年、1973~1978年、1984~1989年、1994~2000年和2008~2019年),不存在明显的趋势变化,其中最长的偏干旱期为1903~1916年(共14年);该重建序列具有较好的时空代表性,1967年、1968年和2003年为该时期的3个极端干旱年,1920年为该时期的1个极端湿润年。波、谱分析结果显示该地区降水存在2.2 a、7~7.7 a以及8~15 a的准周期。另外,研究区降水变化与热带太平洋海温波动(如EnSO、PDO等)和极地海洋涛动(如AO)存在关联并受太阳活动影响。该研究不仅填补了区域空白,延长了该地区的降水记录,还证明阔叶树种白桦也是该地区可靠的树木年轮气候学代用资料。
